美国采购需求：机动三轮车、电动三轮车、电动滑板车、新能源汽车、零配件

I'm looking to get pricing info for electric transportation options, specifically 3 or 4 wheel models. Color isn't a major concern unless it affects the pricing. Could you please provide a detailed quote, including any additional costs for shipping? Additionally, if there are any available features or specifications that could enhance the performance or efficiency of these models, I'd love to hear about them. Looking forward to your prompt response!
